dc.description.abstractThis study aimed to analyze the biological response of titanium surfaces modified by plasma Ar + N2 + H2. Titanium disks grade II received different surface treatments Ar + N2 + H2 plasma, constituting seven groups including only polished samples used as standard. Before and after treatment the samples were evaluated in terms of topography, crystal structure and wettability, using atomic force microscopy, X-ray diffraction, Raman spectroscopy and testing of the sessile drop, respectively. Rich plasma (PRP) was applied to the surfaces modified in culture plates. Images obtained by scanning electron microscopy of the adhered platelets were analyzed to verify the behavior of platelets in the different experimental conditions. We verified that the adition of H2 on plasma atmosphere resulted in more rough surfaces, with round tops. These surfaces, in contrast to that surfaces treated with high concentration of N2, are less propense to platelet aggregation and, consequently, to the formation of thrombus when applied in biomedical devices.
